    "Active resonance cancellation" for closed headphones. Could it make closed-back headphones sound more like open-back headphones?

    Dear Sounds Science subforum, Recently we have seen that headphone manufacturers have developed closed-back headphones which tries to sound more like open-back headphones. One example is the Sennheiser HD 820, which uses concave gorilla glass and sound absorbers to remove resonances associated...

    B&O H9 Discussion and Impressions thread

    Can any B&O expert chime on on what the dot in the midle in front of the driver is? My own guess is that it is the microphone for the noise cancellation, can anyone confirm this? (It would make sense, since it is wired)

    To crossfeed or not to crossfeed? That is the question...

    castleofargh, bigshot and 71 dB, I follow you guys, and I really appreciate your contributions to the sound science forum! @ironmine - I've just installed 112dB redline monitor, and I am really enjoying it with my new HD800S. The xfeed solved the problem with electric guitars sounding diffuse on...

    Sennheiser HD660S... Finally a successor for the HD650?

    I went down to KT radio today to try the 660S again. Unfortunately, they did not have the Sennheiser HD 600 nor the 650 in stock. Instead, the seller suggested me to try and compare it with the Focal Elear, so that’s what I did. Sorry for the poor picture quality. 660S vs. Elear To start...

    Sennheiser HD660S... Finally a successor for the HD650?

    Of course not. I used the HDV 820 and standard cables. In terms of detail retrieval, the 660S is a lot better than the old 650, but it is not a fair comparison, as I am sure it would be closer if the 660S was compared to a new 650. Still, from my memory of the newer iterations of the HD 650 that...

    Sennheiser HD660S... Finally a successor for the HD650?

    Hi Endgame, Please don't get me wrong. The HE-1000 is in many ways a superior headphone to the HD660S. It is just that my in my personal preference I would pick the 660S over the HEK. It could be due to what you would call a more mid-centric sound signature. The HEK has a wonderful bass...

    Sennheiser HD660S... Finally a successor for the HD650?

    So, I just came back from my local hi-fi store "KT Radio" who had just gotten the new 660S in stock today. I compared the headphone to the Hifiman 400s and the HE-1000 V1, and the Sennheiser was definitely my favorite of the three. 660S vs. 400s What struck me the most at first listen was how...

    Does the dryness of headphones cause you irritation?

      Hehe, funny   Maybe the correct term would be tracks with almost no reverb

    Does the dryness of headphones cause you irritation?

    There is no denying anechoic chambers are acoustically uncomfortable, and that listening to speakers in a good listening room is preferable to listening to speakers in an anechoic chamber. Since headphones' interaction with the room is negligible, in some ways headphones should mimic listening...

    In some rare cases headphone cables could make an audible difference

      Very interesting data. What IEM did you use and what were the resistance of the resistors I took a closer look at the picture, and I can see you used a 3 ohm and a 8 ohm resistor. What equipment did you use to measure the frequency response?    Damping factor not only affects frequency...

    They are going fast. I think I was #30, I also aimed to be #1

    The goal is to raise at least £100K. I would be more inclined to back a project when I know the company has a solid track record, rather than backing a project from a new company that might never deliver and loose money. I guess they are raising funds to allow larger production runs, in order to...

      There will also be a wireless head-tracker at some point, but I doubt they will include it in the kickstarter campaign. Maybe it will be a stretch goal?

    Thanks for clearing that up. Now I am really excited for the kickstarter launch on Monday!
